【摘要】：道路交通系统是社会物流实现的重要支撑,其中重要站点的故障可能造成交通系统的运营限于瘫痪,甚至产生重大的经济影响.针对道路交通网络中的相继故障问题,从动静结合的角度分析了道路交通网络的脆弱性.为了检测道路交通网络在相继故障下的脆弱性动态变化,首先建立了道路交通网络的级联反应动力学模型;然后提出该模型中脆弱性的优化设计方案,并利用算法进化得到网络的最优设计;最后利用复杂网络理论得到道路交通网络的网络结构图,通过该算例验证了提出的模型和优化方法的有效性和实际应用性.仿真实验表明该模型和方法能有效地降低交通网络的脆弱性.
[Abstract]:Road traffic system is an important support for the realization of social logistics, in which the failure of important stations may cause the traffic system to be limited to paralysis, and even have a significant economic impact. Aiming at the successive faults in road traffic network, the vulnerability of road traffic network is analyzed from the point of view of dynamic and static combination. In order to detect the dynamic change of the vulnerability of road traffic network under successive faults, the cascade reaction dynamics model of road traffic network is established firstly, and then the optimal design scheme of vulnerability in the model is proposed. Finally, the network structure diagram of the road traffic network is obtained by using the complex network theory, and the validity and practical application of the proposed model and optimization method are verified by the example. Simulation results show that the model and method can effectively reduce the vulnerability of traffic network.
